Mylyn 3.4.2 With 50 Bug Fixes

This is Mylyn’s Helios SR1 service release, featuring 50 bug
fixes. This includes a bug that could occur when removing files
from the context, and a bug that typically caused unwanted files to
appear in the context when a project was checked out from a
repository, or code generated, and the workspace was refreshed
while the task was active. With this service release, large
resource change deltas are now ignored.
